S – A cloud appeared, overshadowing them, and a voice came from the cloud: “This is my beloved Son; listen to him!” 

⁸ Suddenly, looking around, they no longer saw anyone with them except Jesus. 

Mark 9:7–8 CSB

O – Commentary:

Listen to Him (pres. imper.), actually means, “Be obedient to Him.” This reflects the prophecy of Deuteronomy 18:15 (cf. Deut. 18:19, 22 also) and serves to identify Jesus as the new and final Mediator of God’s rule in its present and future form (cf. Ps. 2:4–7; 2 Peter 1:16–19). Jesus succeeded Moses and Elijah, who suddenly disappeared leaving no one except Jesus. Their work was done and they were superseded. Jesus, not Moses or Elijah, is now God’s authorized Ruler and Spokesman.

“Mark,” in The Bible Knowledge Commentary: An Exposition of the Scriptures

The Lord your God will raise up for you a prophet like me from among your own brothers. You must listen to him… ¹⁹ I will hold accountable whoever does not listen to my words that he speaks in my name

Deuteronomy 18:15, 19 CSB

A—God transitions from the prophets to the Messiah. He validates Jesus as the new way to have a relationship with God. When the others disappear, Jesus alone is our way to Him. “Listen to him” becomes more important. Jesus is God’s spokesman, and we are accountable for what he says to us. Our actions will indicate our ability to hear and obey God’s voice.

R – Heavenly Father, we esteem you and lift up your name today.  Please help us to hear your voice and obey.  We are grateful for what Jesus did on the cross, which allowed us to have a relationship with you.  We invite the Holy Spirit to lead us through all we have before us.
